In the embodiment of the invention, the electromagnet 5 is arranged on the adapter of the projectile body or on the gun barrel of the projectile body, so that the existing product can be used, and the cable of the electromagnet 5 is led out from the barrel wall or the gun barrel pipeline.

The pressure reducing valve 3 is also a mature product, and the air inlet end of the pressure reducing valve 3 is connected with the air outlet section 107 of the switch valve 1 by adopting threads, and is sealed. The pressure reducing valve 3 is used for adjusting the pressure of the gas outflow side, so as to adjust the gas flow, and achieve the purpose of stable and controllable gas flow.
In order to cooperate with the control of the piston 6, in the embodiment of the invention, the switch valve 1 is provided with an airflow passage which is communicated with the inside of the gas cylinder 4 and the pressure reducing valve 3; the airflow passage comprises an air inlet section 108, a radial section 102 and an air outlet section 107 which are connected in sequence; the air inlet section 108 is in threaded connection with the air outlet section 107 of the air bottle 4 and is in sealing arrangement, and the air outlet section 107 is connected with the pressure reducing valve 3. The piston 6 is a revolution body, the axis of the piston 6 is arranged along the radial direction of the gas cylinder 4, the piston 6 is provided with a first reducing part 109, the first reducing part 109 can be inserted into and block the radial section 102, when the first reducing part 109 is inserted into the radial section 102, the air flow passage is blocked, the on-off valve 1 is in a closed state, when the first reducing part 109 is separated from the radial section 102, the air flow passage is unblocked, and the on-off valve 1 is in an open state.
The switch valve 1 is further provided with a reset structure, which enables the first reducing portion 109 to be in a state of being inserted into the radial segment 102, namely, when the switch valve 1 is closed when not started, when the projectile body is launched, the electromagnet 5 is started, the piston 6 is attracted, and the effect of the reset structure is overcome, so that the first reducing portion 109 is separated from the radial segment 102.
In the embodiment of the invention, the switch valve 1 is provided with the bushing 106 and the bushing mounting hole, the bushing 106 is completely inserted into the bushing mounting hole along the radial direction of the gas cylinder 4, the radial section 102 is arranged at the bottom of the bushing mounting hole, the bushing 106 is used as a motion constraint structure, specifically, the piston 6 is provided with the second reducing part 110, the second reducing part 110 is installed in the bushing 106, and the second reducing part 110 can move along the radial direction of the gas cylinder 4 in the bushing 106. In addition, to ensure a clear flow path, the outlet section 107 passes through the sidewall of the liner mounting bore and communicates with the radial section 102.
In order to simplify the whole device, in the embodiment of the invention, the reset structure is the switch spring 103 in a compressed state, one end of the switch spring 103 is abutted against the bushing 106, the other end is abutted against the second reducing portion 110, and when the electromagnet 5 does not operate, the switch spring 103 pushes the first reducing portion 109 of the piston 6 into the radial segment 102.
Because the device is arranged in the projectile body, when the projectile body is separated from the launching device and the electromagnet 5 cannot be launched together with the projectile body, the embodiment of the invention is provided with the locking structure to enable the switch valve 1 to be in an open state, and concretely, the locking structure comprises a locking hole and a locking pin 104, and the side wall of the second reducing part 110 is provided with the locking hole along the radial direction of the piston 6; the bushing 106 is provided with a locking pin 104, the locking pin 104 being insertable into the locking hole by means of a locking spring 105; when the electromagnet 5 is activated, the piston 6 moves under the action of magnetic force, the first diameter-changing portion 109 is withdrawn from the radial segment 102, and when the two are completely separated, the locking pin 104 is inserted into the locking hole, at this time, even if the electromagnet 5 no longer applies force to the piston 6, the piston 6 is locked in the current position, and the air flow path is in a clear state.
It should be noted that, considering that there is a great overload acceleration and deceleration process during the launching and underwater navigation of the underwater projectile, the single locking structure is likely to disengage from the locking pin 104 and the locking hole due to the inertial force, so that the piston 6 is inserted into the radial segment 102 again under the action of the switch spring 103, blocking the airflow passage, and preventing the airflow from being reduced.
To prevent this, the locking structure is provided with at least 2 groups and is arranged at different positions along the circumference of the piston 6, preferably the locking structure is provided with 2 groups, each arranged between the piston 6 and the bush 106 in front and back in the axial direction of the cylinder 4, to ensure that the piston 6 is not unlocked, so that the device of the invention can still continuously and stably output gas for gas drag reduction after the projectile is launched.
Since the piston 6 is a revolution body, in order to prevent the piston 6 from rotating, the locking hole and the locking pin 104 are dislocated circumferentially, so that the locking structure is disabled.
In view of the fact that the device of the present invention is used for the launching of underwater projectiles, it is desirable to prevent the ingress of liquids and, in addition, to prevent the leakage of gases from other locations. In the embodiment of the present invention, the first reducing portion 109 is provided with a first sealing ring, and the first sealing ring can seal between the first reducing portion 109 and the radial segment 102; the second reducing portion 110 is provided with a second seal ring, which can seal between the second reducing portion 110 and the bushing 106.

In the embodiment of the invention, the inflation valve 2 is composed of an inflation connector 201 and a one-way valve 202, wherein the inflation connector 201 and the one-way valve 202 are made of aluminum alloy materials, and preferably magnesium alloy materials, so that the weight is reduced. The inflation connector 201 is in threaded sealing connection with the one-way valve 202, and one end of the inflation connector 201 is in threaded sealing connection with one end of the gas cylinder 4. In the process of inflation, the joint of the inflation valve 2 is connected with an inflation pipeline, the one-way valve 202 is used for realizing one-way flow of gas, when the lateral pressure of the joint of the inflation valve 2 is larger than the lateral pressure of the gas cylinder 4, the one-way valve 202 is in an open state, and when the lateral pressure of the joint of the inflation valve 2 is smaller than the lateral pressure of the gas cylinder 4, the one-way valve 202 is in a closed state.

When using the embodiments of the present invention:
firstly, the gas cylinder 4 is inflated, after the joint of the inflation valve 2 is connected with an inflation pipeline, the gas cylinder 4 is inflated, at the moment, the lateral pressure of the joint of the inflation valve 2 is larger than the lateral pressure of the gas cylinder 4, the one-way valve 202 is in an open state, after the pressure in the gas cylinder 4 reaches the set pressure, the inflation is stopped, the gas pressure in the inflation pipeline is removed, at the moment, the lateral pressure of the gas cylinder 4 is larger than the lateral pressure of the joint of the inflation valve 2, and the one-way valve 202 is in a closed state.
Before underwater launching, the electromagnet 5 is not electrified in the initial state, and the switch spring 103 and the locking spring 105 are in a compressed state; the piston 6 is inserted into the radial section 102 by the first reducing part 109 under the action of the switch spring 103, and the first sealing ring seals between the first reducing part 109 and the radial section 102 to realize the sealing of the airflow passage; the lock pin 104 is completely restricted inside the bush 106 by the lock spring 105 and the wall surface of the piston 6, and the lock pin 104 is pressed against the side wall of the second diameter-changing portion 110, and the on-off valve 1 is closed.
